HP 717973-B21 800GB 2.5" SATA enterprise SSD

HP 800 GB 2.5-inch SATA enterprise SSD

This refurbished HP 717973-B21 drive provides 800 GB of capacity in a 2.5-inch form factor with a SATA 6Gb/s interface. It uses MLC flash memory and is built for server and storage-array workloads that demand consistent write endurance. The drive suits administrators replacing failed units or expanding existing SATA-based arrays.

Sustained write behaviour and latency

MLC flash and the enterprise-grade controller maintain steady throughput during extended write sequences rather than throttling after a short burst. The quoted seek time of .1 ms reflects low latency for random read operations typical of database and virtualization workloads. This consistency helps prevent performance dips during heavy I/O periods.

Thermals, noise and power draw

The solid-state design has no moving parts, so the drive operates silently in normal use. Its slim .38-inch height and 100 g weight allow dense packing in 2.5-inch bays without adding significant thermal load. Power consumption stays within standard SATA limits, simplifying cooling planning for rackmount chassis.
